We make the installation incredibly simple! You only need to paste your Facebook Pixel ID into the settings field, and that's it. Normally, the code can be quite difficult to install, as it requires a lot of custom code for all the different events (pageview, signup, view cart, purchase, etc).

Yes, you can still write custom code to track your own custom events beyond these standard events! In the editor, go to Settings > Advanced > Custom Code > Footer Code and you can write your tracking code there. See Facebook's guide for more info.
